SPRING ASSEMBLY FOR MATTRESSES AND THE LIKE Filed Jan. 7, 1932 NVENTORLawrence H Hcuar ATTORNEYS Patented May 9, 1933 UNITED STATES PATENTOFFICE LAWRENCE H. BLEUER, OF DETROIT, MICHIGAN, ASSIGNOB TO L. A. YOUNGSPRING 8; WIRE CORPORATION, OF DETROIT, MICHIGAN SPRING ASSEMBLY FORMIATTRESSES AND THE LIKE Application filed January 7, 1932.

The main objects of this invention are:

First, to provide a spring assembly or spring filler unit formattresses, pillows and the like which is very resilient and at the sametime the springs are efl'ectively supported in upright position, andalso one in which the sides of the covering are effectively' supportedand prevented from sagging or buckling between or becoming interlockedwith the side border springs of the unit.

Second, to provide a unit of this character in which the edgesare,.formed so that they are somewhat stifi'er than the center or bodyportion of the unit.

Third, to provide a spring assembly of this character which can bereadily adjusted in width to meet the particular requirements of themattress maker without varying the number of rows of springs or changingthe diameters of the springs.

Objects pertaining to details and economies of my invention willdefinitely appear from the description to follow. The invention isdefined and pointed out in the claims.

A structure which embodies the features of my invention is clearlyillustrated in the accompanying drawing, in which:

Fig. 1 is a perspective view of a mattress embodying my fillepnnit orspring assembly with the upholstery thereof partially broken away.

Fig. 2 is an enlarged fragmentary view illustrating the relation of theborder springs to the body springs and the connections to these parts.

Fig. 3 is a fragmentary elevation of one of the border springs.

In the embodiment of my invention illustrated the mattress comprises theupholstery or covering 1 which is provided with a suitable filler shownconventionally, and the casing 2 of fabric designed to house the springassembly and to be inserted therewith into the upholstery.

My improved assembly in the embodiment Serial No. 585,211.

illustrated comprises a plurality of body springs 3 of the spiral orhelically coiled type having the end coils 4 thereof provided withoffsets 5 on opposite sides. The structure illustrated has pairs ofthese offsets.

The body springs are arranged in rows with the ofi'setsof adjacentsprings in alternating relation so as to bring the bights of theofl'sets in alinement. The body springs are connected by helical tiemembers 6 which embrace or encircle these alined offsets, the engagementbeing efiected by rotating the tie members. This provides a veryresilient connection for the body springs and at the same time allowsthe springs to yield freely.

The border springs 7 are of the helical or spiral type, the coilsthereof being elongated and relatively narrow and having substantiallystraight outer reaches 8. The end coils of these border springs areprovided with 65 inwardly projecting arms 9 which terminate in offsets10 corresponding to the ofl'sets' 5 of thebody springs and arranged inalined relation therewith to receive the helical tie members 11 whichcorrespond to the tie members 6.

The border tie members 12 encircle the outer reaches of the end coils ofthe border springs.

With this arrangement the several springs 75 of the assembly areefl'ectively supported and at the same time the unit is very flexible.The outer or border springs provide a substantially continuous grid-likesupport forthe edge of the covering as the ends of the springs may bearranged quite close together and their outer reaches lie insubstantially the same plane.

By thus forming the border springs they may be readily somewhat stifferthan the body springs which is a desirable feature.

Another advantage of the construction is that the length of the arms 9can be easily varied providing a spring unit of the desired widthwithout the necessity for changing the 99 diameters of the body springs,providing special filler springs, or other means resorted to in theproduction of mattress and cushion filler units.

I have illustrated and described my improvements as embodied in amattress assembly or filler unit. I have not attempted to illustrate theparts in their relative proportions and the parts in Fig. 1 areconventionalized. My invention is readily adapted for a variety of useswhich I have not attempted to illustrate and describe as it is believedthat this disclosure will enable those skilled in the art to embody oradapt the same as may be desired.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. A spring assembly for mattresses and the like comprising spiral bodysprings arranged in rows and having oppositely disposed ofi'sets intheir terminal coils, helical tie members encircling the ofl'sets ofadjacent rows of said body springs, spiral border springs havingelongated and relatively narrow coils disposed in alined parallelrelation to the side of the assembly and with the ends of the coils inclose proximity providing a substantially continuous covering supportingsurface, the end coils of said border springs terminating in. inwardlyconverging arms having offsets at the ends thereof disposed adjacent theofi'sets of'the adjacent row of body springs, helical tie membersencircling the oifsets of said arms and adjacent body springs, andhelical border tie members encircling the outer reaches of the end coilsof the border springs.

2. A spring assembly comprising spiral border springs having elongatedand relatively narrow coils disposed in alined parallel relation to theside of the assembly and with the ends of the coils in close proximityproviding a substantially continuous covering supporting means, the endcoils of said border springs terminating in inwardly projecting armshaving ofisets therein, a row of body springs having offsets in the endcoils thereof disposed adjacent the ofi'sets of said arms, helical tiemembers encircling the oilsets of said arms and adjacent body springs,and helical border tie members encircling the outer reaches of the endcoils of the border spring.

3. spring assembly for mattresses and the like comprising spiral bodysprings arranged in rows and having oppositely disposed ofl'sets intheir terminal coils, helical tie members encircling the ofi'sets ofadjacent rows of said body springs, spiral border springs havingelongated and relatively narrow coils disposed in alined parallelrelation to the side of the assembly and with the ends.

of thescoils in close proximity providing a substantially continuouscovering supporthand.
